What are some best practices for efficiently extracting text from large server logs in PHP without compromising performance?

When extracting text from large server logs in PHP, it's important to use efficient methods to avoid compromising performance. One approach is to use regular expressions to search for and extract specific patterns or keywords from the logs. Additionally, utilizing functions like `preg_match_all()` can help streamline the extraction process. 

// Example code snippet using regular expressions to extract text from server logs efficiently
$logData = file_get_contents('server.log');
$pattern = '/(ERROR|WARNING): (.*)/';
preg_match_all($pattern, $logData, $matches);

foreach ($matches[0] as $match) {
    echo $match . "\n";
}
